CapEx Reserves: Why Guessing Destroys Your Exit Multiple

You run the numbers on a 150-unit deal. The pro forma looks clean. Cash flow is solid. Everything points to a smooth exit in year three. Then you close. Six months in, the roof needs $80K in repairs you didn't see coming. A year later, the HVAC systems start failing unit by

Why Most Investors Get Debt Assumptions Wrong (And How It’s Destroying Their Returns)

Most investors treat debt like it’s set in stone. They plug in today’s rates, assume they’ll stay constant, and call it good. This is how deals that look amazing on paper turn into cash-eating disasters. The Static Debt Trap Here’s the truth: debt is dynamic, not static. Interest

Why Most Investors Get Market Analysis Wrong and How It’s Killing Their Returns

Most investors think market analysis means pulling rent comps and calling it done. They’re wrong. And it’s costing them serious money. Real market analysis isn’t about what rents are today. It’s about understanding the economic forces that will drive rents tomorrow. Here’s what happens when you get it

Why Most Investors Fail at Rent Projections (And How It’s Destroying Their Deals)

Most investors think rent projections are about finding comparable units and adding 2-3%. That’s not rent projection. That’s wishful thinking.

Most investors use 40% expense ratios like it’s some kind of universal law. It’s not. And this lazy assumption is quietly destroying deals.

Why Your 5% Vacancy Assumption Is Wrong (And How to Fix It)

Most investors use 5% vacancy across the board. Every deal. Every market. Every property type. It’s lazy. And it’s costing you money. Here’s the truth: vacancy rates aren’t universal. They’re hyperlocal. And they change. A Class A property in downtown Austin has different vacancy than a Class C

FIELD NOTE

Why Cap Rates Don’t Tell the Whole Story in Multifamily Investing

Most investors think cap rates are simple math. Buy at 5%, sell at 4%, make money. Wrong. Cap rates aren’t just numbers on a spreadsheet. They’re risk assessments disguised as percentages. Here’s what happens when you get this wrong. You chase “high cap rate” deals in sketchy neighborhoods. You overpay for “stable” assets

The Right Way to Use Rent Comps in Multifamily Real Estate

Most investors treat rent comps like a quick task. They search a few properties, pull some numbers, and move on. But that approach is exactly how bad deals slip through.

Why Uncertainty in Underwriting Can Cost You

One of the biggest mistakes I see investors make when underwriting deals? They’re uncertain about their numbers—where they come from, why they’re used, or where they lead. And that uncertainty?

Why Surface-Level Underwriting Could Be Costing You Big in Multifamily Investing

Too many investors jump into multifamily deals with confidence, only to realize later they missed something critical. They assumed a surface-level understanding would be enough.
